A device for the transport of a gas sample into the measuring chamber of a detector for the determination of the portion of a component in a gas, and in particular of alcohol in respiratory air, includes a piston-cylinder unit serves as the transport element. The sample is used as completely as possible for the signal analysis of the sensor at the beginning of the sampling process. The measuring-sensitive surface of the sensor comprises a part of the wall of the cylinder chamber of the transport unit which serves as the measuring chamber. The path on which the sample is guided between the inlet and the cylinder chamber is defined by a deviation baffle provided along the measuring-sensitive surface of the sensor.
